Description
This substantial Class IV rapid represents the most significant whitewater challenge on the Atigun River, featuring a complex series of powerful hydraulics and technical maneuvering between large, jagged mid-river rocks. Paddlers must carefully navigate a technical entry with a tight main channel that quickly develops into a steep, turbulent descent with unpredictable lateral waves and potential pour-over hazards that demand precise boat control and immediate route selection.
